ABSTRACT
Lubrication is essential for any kind of machinery onboard ships. For example, the lubrication system of the main engine is responsible for lubricating and cooling the internal parts, which, when acting relative to each other, create immense friction and heat, which can result in the overheating of parts. Lubrication not only provides cooling but also the removal of any debris or impurities. There are several types of lubrication systems available including hydrodynamic lubrication, hydrostatic lubrication, boundary lubrication, and elasto-hydrodynamic lubrication. In this chapter, we will very briefly discuss the role and function of each of these lubrication systems.
